发明名称 Sensorarrangemang
摘要 The present invention relates to a sensor arrangement adapted to evaluate an instant quality related value of a measured liquid sample ("S") by applying a discontinuous and/or a continuous signal ("V") to a number of electrodes ( 2, 3, 4 ), which are in electrical contact with said liquid sample ("S"), where a current ( 11, 12, 13 ), or equivalent quantity, measured at different potentials (voltage levels) between a reference electrode ( 3 ) and at least one working electrode ( 2 or 4 ), is evaluated at least at such time sequences where said measured current reflects the presence of any redox-active component, that may either be oxidation, reduction or neutral, at said working electrode ( 2 or 4 ). Said reference electrode ( 3 ) and said working electrode or electrodes ( 2, 4 ) are coordinated to simultaneously be immerged by a flow or stream of liquid samples ("S 1 ", "S", "S 2 "), that said reference electrode ( 3 ) and said working electrode or electrodes ( 2, 4 ) are connected to an electronic arrangement ( 5 ), and that said electronic arrangement includes a first circuit ( 5 a), for evaluating said instant quality related value, and a second circuit ( 5 b), for evaluating any chemical and/or biological changing in said measured instant quality related value, in relation to a stored ( 5 c) reference value.
